COSRX AC Collection Acne Patch (26 Patches)

An advanced, high-adherence clinical hydrocolloid spot treatment engineered to absorb pus, fluid, and exudate from active inflammatory blemishes while sealing the skin environment. Moving beyond standard circular pimple stickers, these custom-carved oval patches feature a gradient structure with an ultra-thin, tapered border that locks onto facial contours.

The medical-grade hydrocolloid matrix is uniquely infused with Centella Asiatica (Cica) Extract, enabling a dual-action therapeutic process: extracting fluid through vacuum-like absorption while continuously dripping calming, skin-remodeling botanical nourishment right into the epicenter of the breakout.

Most conventional acne patches are perfectly circular and uniformly thick, which causes them to lift, wrinkle, and slide off the moment you talk, smile, or sleep—especially when placed near the mouth or jawline.

COSRX completely re-engineers this physical limitation with the AC Collection Acne Patch using "Tapered Gradient Architecture." The patch is thicker in the center to hold maximum impurity-absorbing hydrocolloid power, but thins down to a microscopic edge at the border. This design creates a vacuum seal that stays firmly in place through facial movement. Furthermore, instead of just acting as a passive bandage, it is heavily infused with Centella Asiatica Extract, combining fluid extraction with active tissue healing to accelerate recovery and prevent dark marks or structural pitting.

Perfect for anyone dealing with open whiteheads, newly popped pimples, surface blemishes, and deep, painful cystic bumps that sit on uneven areas of the face. It is an absolute life-saver for compulsive skin-pickers who accidentally worsen acne by touching their faces. If you struggle to keep traditional round patches adhered to highly mobile or curved zones—such as the jawline, chin, hairline, or around the nose—these high-adherence sheets provide a secure, seamless seal.

Prep: Wash your face thoroughly and ensure the target blemish zone is completely clean and 100% dry. (Do not apply any toners, essences, or creams beforehand, as surface moisture will compromise patch adhesion).

Select: Choose a patch size from the sheet that is slightly larger than the blemish you intend to treat.

Apply: Carefully peel the patch off the protective film and center it over the pimple. Press down gently around the tapered edges for 3 to 5 seconds to lock in the vacuum seal.

Remove: Leave the patch on for 8 to 12 hours (or overnight). Once the clear center turns completely opaque white with absorbed impurities, gently peel it off from the edges and discard.

Pro Tip (The Flawless Daytime Concealer Base): Because these patches feature incredibly thin, translucent borders and a matte, skin-like finish, they are practically invisible. Apply the patch onto clean, dry skin in the morning before your skincare routine. Once it is sealed onto your face, you can safely apply your toners, moisturizers, sunscreen, and liquid concealer or foundation directly over the top of the patch. This hack provides a beautifully smooth makeup canvas while protecting the raw, open acne wound from being irritated or clogged by cosmetics during the day.
